Given numbers are 7946,2112
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7946,2112 is 8390976.
Find LCM of 7946,2112 with Prime Factorization
| 2 | 7946, 2112 |
| 3973, 1056 |
Multiply the prime numbers at the bottom and the left side.
2 x 3973 x 1056 = 8390976
Therefore, the lowest common multiple of 7946,2112 is 8390976.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
7946 x 2112 = 16781952
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
7946 : 1, 2, 29, 58, 137, 274, 3973, 7946
2112 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 32, 33, 44, 48, 64, 66, 88, 96, 132, 176, 192, 264, 352, 528, 704, 1056, 2112
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7946,2112, is 2.
Now, the common factors can be found like this.
7946:2x 29x 137
2112:2x 2x 2x 2x 2x 2x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 16781952/(2x1)
LCM = 16781952/2
LCM = 8390976
Thus, we can understand that the LCM of 7946,2112 is 8390976.
